mpas_tools.mesh.creation.signed_distance.mask_from_geojson(fc, lon_grd, lat_grd)[source]

Make a rasterized mask on a lon/lat grid from shapes (geojson multipolygon data).

Parameters
  • fc (geometrics_features.FeatureCollection) – The regions to be rasterized

  • lon_grd (numpy.ndarray) – A 1D array of evenly spaced longitude values

  • lat_grd (numpy.ndarray) – A 1D array of evenly spaced latitude values

Returns

mask (numpy.ndarray) – A 2D mask with the shapes rasterized (0.0 outside, 1.0 inside)
